• T-Ray Science licenses MIT's terahertz technology

    There is a growing interest in the detection capabilities of terahertz technology, and a Canadian company licenses an NIT-developed detection system that can be used to detect a continuous-wave (cw) THz signal

  • UAV-based anti-missile defense appears doomed

    DHS’s Project Chloe envisioned a UAV-based system to defend commercial airlines against shoulder-fired missiles; Northrop Grumman tests show the system to be more complex, and costlier, than originally anticipated

  • Fingerprint "developer" can read a letter from its envelope

    U.K. researchers find that disulfur dinitride polymer turned exposed fingerprints brown, as the polymer reaction was initiated from the near-undetectable remaining residues; what is more, traces of inkjet printer ink can also initiate the polymer, allowing detectives to read a letter from the residue it left on the envelope

  • CSIRO wireless sensor commercially available

    Wireless sensor networks are used in more and more homeland security roles such as monitoring water quality at sprawling water facilities and in perimeter defense of critical infrastructure facilities; they can also help keep the environment healthy

  • "Digital DNA" to fight cyber crime

    Scottish researchers develop what they call “digital DNA”: It is based on analyzing the way in which users access data on their computers and then creating a digital fingerprint that is unique to each user

  • The priorities of DHS's Science and Technology Directorate

    DHS’s Science and Technology Directorate is known for its restless, entrepreneurial spirit; it has a $830 million dollar budget, and 250 projects under development at any one time

  • Earthquake's trampoline effect

    During earthquakes the ground not only shakes from side to side, but also bounces up and down; this has important implications for designing quake-proof structures

  • Where is James Bond when we need him?

    The villains James Bond was fighting — Dr. No, Goldfinger, and Blofeld — looked improbable in the 1960s; these miscreants of globalization — part master criminal, part arms smuggler, part terrorist, part warlord —are now the stuff of reality

  • Better chemical sensor emulates animals' noses

    A new “electronic nose” is more adept than conventional methodologies at recognizing molecular features even for chemicals it has not been trained to detect

  • Using laptops to detect earthquakes

    Laptops have a small accelerometer chip built into them in order to protect the delicate moving parts of the hard disk from sudden jolts; same chip is a pretty good earthquake sensor, too

  • Tiny gas sensor to detect explosive vapors and chemical agents

    EU-funded project aims to develop a tiny sensor — sensor will be less than two centimeters in length and at least twice as sensitive as other sensors of its size

  • Small hand-held detector for security, health threats

    Researchers develop the world’s smallest detection system: The size of a shoe box, the complete mass spectrometer identifies tiny amounts of chemicals in the environment

  • U.K. project examines the idea of a nuclear-powered passenger aircraft

    As worries about the rising price of oil and climate change grow, so grows the interest in nuclear power — but not only for ground-based power generation; a U.K. government-funded project examines the idea of nuclear-powered passenger plane

  • Sun's growing brightness a threat to Earth

    The Sun is slowly getting brighter and warmer; in seven billion years it will engulf Earth — but much sooner, in 1.1 billion years, the Sun will grow 11 percent brighter, raising average terrestrial temperatures to around 50 °C, causing oceans to evaporate; the solution: move Earth away from the Sun

  • Messaging pictures as a safety device

    A Pittsburgh-based startup allows you to take pictures of threatening individuals you may encounter in hairy situations, and message these pictures to a secure “vault”; if you do not come back to your home or office by a specified time, the date- and time-stamped pictures are made available to the police
